Rent & eviction protection

Is 1840-1842 Clement St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1911

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1911
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 1840-1842 Clement Street is a two-story, multi-family residential building with commercial space, constructed in 1911 and currently owned by the Hu Lenox Family Trust. The building underwent significant transformation in 2011-2012, transitioning from a former restaurant to a stained glass workshop, which included substantial renovations such as new storefronts, structural support modifications, and the installation of new skylights. During this period, various infrastructure improvements were completed, including water pipe replacement, electrical upgrades (installing lighting, switches, receptacles, smoke detectors), plumbing work (including bathroom remodels and area drains installation), and HVAC improvements with a new furnace installation.

Of particular concern is a complaint filed in July 2020 regarding the converted commercial space, raising questions about fire safety systems (specifically sprinklers), ventilation concerns related to fume management, and compliance with setback laws, though this complaint is currently listed as not active. The building's maintenance history shows regular responses to street cleaning and graffiti issues, particularly in 2022, with multiple 311 calls for general cleaning and graffiti removal, suggesting ongoing exterior maintenance challenges. Recent building improvements included street space permits and utility work, though there appears to be a lapse in permit status for some plumbing and electrical work from 2012. A historical fire complaint from 2009 was resolved on the same day, with conditions corrected.

Risk rating

How 1840-1842 Clement St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
15thpercentile

Out of 2250 buildings in this neighborhood, 1912 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
